This post http://www.daemon.de/blog/2014/12/30/383/re-perl-jam-exploiting-20-year-old-vulnerability-31c3/ details a claim that perl has a security flaw, and rejects that claim.

Apparently this:

my @a = qw(8 foo 666);
my %h = (foo => 100,
     bar => 333,
     san => @a);
print Dumper(\%h);

$VAR1 = {
          'san' => 8,
          'bar' => 333,
          'foo' => 666
        };

Is expected behaviour and not a problem. Happy to accept that, but can someone talk me through it? I've been working with perl for many years and never heard the word "dissolve" used before.
